<h3 id="rationale">Rationale:</h3>
<p>ShellCheck has found a <code>$"(</code> or <code>$"{</code> . This is
most likely due to flipping the dollar-sign and double quote:</p>
<pre><code>echo $&quot;(cmd)&quot;  # Supposed to be &quot;$(cmd)&quot;
echo $&quot;{var}&quot;  # Supposed to be &quot;${var}&quot;</code></pre>
<p>Instead of quoted substitutions, these will be interpreted as
localized string resources (<code>$".."</code>) containing literal
parentheses or curly braces. If this was not intentional, you should
flip the <code>"</code> and <code>$</code> like in the example.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>If you intentionally wanted a localized string literal
<code>$".."</code> that starts with <code>(</code> or <code>{</code>,
either <a href="ignore.html">ignore</a> this error or start it with a
different character.</p>
